Answer:
x = negative 1 plus-or-minus StartRoot 17 EndRoot
Step-by-step explanation:
Given:
We need to solve for x.
First we will solve L.H.S
Factorizing the equation we get;
Now Things which are equal to the same thing are also equal to one another. Since
then, according to the law of transitivity,
Now, applying the Square Root Principle we get:
Now Square root and square gets cancelled.
Since a square root has two values, one positive and the other negative.
Hence Final Answer is .
Hello from MrBillDoesMath!
Answer:
a(n) = 12 - 3(n-1) , n = 1,2,3.,,
Discussion:
The terms are 12, 9, 6, 3 so we are apparently subtracting 3 from each succeeding term. . Hence
a(n) = 12 - 3(n-1) , n = 1,2,3.,,
Thank you,
MrB
Recall the formula for determining the interest using simple interest
Convert the rate into decimal form by dividing by 100%
Substitute the following values
P = $1300, r = 0.07, t = 6/12 (12 months in a year, only 6 months has passed)
Therefore, Margo will pay back $45.50 in interest.
The difference quotient is -6. See photo for the work.
